ADJUSTABLE HEAD FOR GOLF CLUBS;

Application filed July 7, 1926. Serial No. 120,899.

My invention relates to improvements in golf clubs, having adjustable heads, and it consist-s of a eombmatlon, construction, andarrangement, hereinafter described and claimed. I

An object of my invention is to provide a golf club having an adjustable head, in which the parts are so'arranged as" to have the force of the impact'of the golf ball upon the blade tend to tighten the parts for more rigidly securing the parts together. i

A further object of my invention is to provide a device of the type described, in which the blade may be adjusted at various angles, or may be entirely removed and a new blade substituted therefor.

Other objects and advantages will appear in the following specification, and the novel features of the device will be more particularly pointed out in the appended claims.

' My invention is illustrated in the accompanying drawing forming a part of this application in which,

Figure 1 is a vertical section through the device.

Figure 2 is a front elevation of the device and,

Figure 3 is a view showing a portion of the locking pin. t

Figure 4 is a top plan view of a modified form of the device.

Figure 5 is an enlarged detail of parts shown in Figure 1.

In carrying out my invention I provide a ferrule which is designed to receive the handle 2.

The ferrule has a reduced tubular portion 3 which receives a screw 4. The screw 4 has a left hand thread for a purpose hereinafter described. A tubular casing 5 is rotatably mounted upon the outside of the portion 3 and has its end 6 crimped into' a groove 7, whereby the casing 5 is rotatably secured to the ferrule 1.

A blade 9 has a dove-tailed slot- 8 therein for receiving a projection 10, carried by the screw 4. The projection 10 permits the blade 9 to be swung into the desired angle. It will be noted in Figure 2 that the projection 10 has inclined walls 11 limiting the movement of the blade 9. The walls 8 of the blade contact with the walls 11 when the blade has been swung through a predetermined distance.

This means for securing the blade in positioncomprises a serrated edge 12,.inthe1 blade 9 engaging with a serrated edge 13 on'the easing 5. The edges l2 and 13are arcuate shapeand tapered for. adding. great-5 er strength tothe device. The edged?) has agroove 14 which preventsthe'binding ofthe blade in ,the casing when the screw 4 is released.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. To secure the blade 9 in place, the blade is first mounted upon the projection 10 and then the screw 4 is inserted into portion 3. I rotation of the handle 2 to the left will draw the screw into place and will cause the serrated portions 12 and 13 to mesh.

To adjust the blade 9 to the desired angle it is merely necessary to insert the blade in the palm of the left hand and then with the right hand make a one-half turn of the handle 2 to-the right. This will release the blade 9 sufliciently to permit the blade to f be swung into the desired angle The casing 5 is providedwith graduations 14' and the blade 9 is providedwith a mark '15 for this purpose.

It will be noted that the head of the golf club will tend to pivot the casing 5 in a direction for tightening the screw 4. Figure 1 shows that the blade 9 may be of various shapes so as to extend at different angles in the manner shown. Any of the blades 9 nay be delicately adjustedto the desired 10 t.-

It is further to be noted that the concentration mass is at the desired point regardless of the angle intowhich the head 9 is swung. This construction causes the club to have the same feel at all the positions which the head 9 may take with respect to the handle 2. This permits the golfer to have hismind clear to measure the force of the blow. and the direction of the shot. Due to the fact that the same club is the angle formed by the shaft and blade will not vary so greatly, as the form of the device shown in Figure 4.

I claim:

1. A golf club comprising a handle, a casing carried by said handle, a left handed screw receivable in said casing, said screw having a projection, a blade having a recess for receiving said projection whereby said blade is secured to said screw, said blade being pivotally mounted on saidprojection, cooperating means carried bysaid casing and said blade for securing said blade in angular position with respect to said casing, said screw when moved into position bringing the means of said casing and of said blade into abutting relation, whereby said blade is secured in place.

2. A golf club comprising a handle, a blade having a wedge shaped recess therein,

a left handed screw removably secured to said handle, a wedge shaped projection carried by said screw and being removably receivable in said recess.

3. A golf club comprising a handle, a blade having a wedge shaped recess therein, a left handed screw removably secured to said handle,a wedge shaped projectioncan ried by said screw andibeing removably receivable in said recess, and means for locking said blade in angular position with respect to said handle.

In testimony whereof I have affixed my signature. i I
